Boost went from 12 to 6 lbs

So this weekend I took car out for a nice drive through national forest.. first time really having car out and getting on it since supercharger install. On the way back from drive I started getting on it little harder and notice that it was making only about 5 to 7 lbs of boost. When before it was making around 12lbs.. I checked the belt I can't really see anything wrong but I don't know.. it was a 50 degree day so I wouldn't think heat soak.. any ideas or advice would be very appreciated. . This is my first supercharger car so not very familiar. .

Belt or boost leaks would be first guess. Check bypass valve that it's not stuck open either. What kind of setup? My boost went up in the cold.

It's a lsa supercharger. How do I check to see if bypass is stuck open?

This is how you adjust it -- using the $12 tool:

Did you go Full Throttle?

You will not reach full boost unless your at full throttle.

Bypass problem or belt problem are most likely.
